How will Yemen’s crisis affect US foreign policy?

Yemen has a rebel army operating within its borders, its economy is collapsing, and its latest government just resigned. It appears to be a pretty weak building block for a regional anti-terrorism strategy, but the United States has poured hundreds of millions of dollars into Yemen, regardless, and the Saudis have given some $4 billion in aid. 

Yemen is Exhibit A for what's hard about making peace in a rough neighborhood — a cobbled-together country split ethnically, regionally and religiously. Its factions get help from different countries with different interests in the outcome, and those countries also happen to hate one another. 

Yemen is poor, unstable and unsafe, a training ground for extremist fighters. And it's pulling the United States into a conflict with no clear end.
